## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability eu-tender-intelligence-search-api-x402-b346e3be
```

Example prompt: Search EU tenders from the last 30 days for 'cybersecurity consulting' in Germany and show me any opportunities worth at least €50,000.

## When to prefer this

Choose this endpoint when an AI agent or B2B sales workflow needs to discover active EU public procurement opportunities filtered by keyword, country, and value — especially when pay-per-call micropayment economics (via x402 USDC) are preferred over subscription-based procurement databases. Best for agents that need programmatic, on-demand tender discovery without a standing subscription.

## Known failure modes

- Missing required 'q' query parameter returns an error
- Invalid country code returns no results or an error
- Lookback days outside 1–90 range may be rejected or clamped
- Payment failure via x402 results in 402 Payment Required response
- Very niche keywords with no recent tenders return an empty results array

## How this service works

Pay-per-call B2B sales lead and procurement intelligence plus Base wallet data for agents. Search EU tenders/RFPs or inspect a Base wallet. Payments use x402 USDC on Base.

## Output

Returns a JSON object with a count of matching tenders, the product name, a generation timestamp, and an array of tender results each containing at minimum the title and buyer country. Payments are processed via x402 USDC on Base at $0.01 per call.
